Title (EN) HEAD-UP DISPLAY DEVICE FOR VEHICLE
(FR) DISPOSITIF D'AFFICHAGE TÊTE HAUTE POUR VÉHICULE
(JA) 車両用ヘッドアップディスプレイ装置
Abstract:
(EN) A head-up display device (1) for a vehicle is provided with a light source device (11), a display panel (12) and an illumination optical system (13). The display panel (12) is transmissive. The illumination optical system (13) guides illumination light (X0) from the light source device (11) to the display panel (12). The illumination optical system (13) includes a lens module (131). The lens module (131) includes one or more lenses (131a) located on the optical axis (O) of the illumination light. The light source device (11) emits an illumination light (X0) in which the larger the angle of a light ray related to the optical axis (O) is, the lower the luminance. The lens module (131) has an optical property such that in the illumination light (X0), as the angle of a light ray related to the optical axis (O) increases, the density is increased and transmitted.
(FR) Le dispositif (1) d'affichage tête haute selon l'invention comporte: un dispositif (11) de source lumineuse; un panneau (12) d'affichage; et un système optique (13) d'éclairage. Le panneau (12) d'affichage est de type transmissif. Le système optique (13) d'éclairage guide un rayon lumineux (X0) depuis le dispositif (11) de source lumineuse au panneau (12) d'affichage. Le système optique (13) d'éclairage contient un module (131) de lentille. Le module (131) de lentille contient au moins une lentille (131a) placée sur l'axe optique (O) du rayon lumineux. Le dispositif (11) de source lumineuse émet en sortie un rayon lumineux (X0) dont la luminance est faible plus l'angle du rayon avec l'axe optique (O) est grand. Ce module (131) de lentille présente une spécificité optique telle que dans le rayon lumineux (X0), plus l'angle du rayon avec l'axe optique (O) est grand, plus la densité est augmentée.
(JA) 車両用ヘッドアップディスプレイ装置(1)は、光源装置(11)と、表示パネル(12)と、照明光学系(13)と、を備える。前記表示パネル(12)は透過型である。前記照明光学系(13)は、前記光源装置(11)からの照明光(X0)を前記表示パネル(12)に導く。前記照明光学系(12)は、レンズモジュール(131)を含む。前記レンズモジュール(131)は、前記照明光の光軸(O)上に位置する1つ以上のレンズ(131a)を含む。前記光源装置(11)は、前記光軸(O)となす角が大きい光線ほど輝度が低い照明光(X0)を射出する。前記レンズモジュール(131)は、前記照明光(X0)のうち前記光軸(O)となす角度が大きい光線ほど密度を高めて透過させる光学特性を有する。
